Are there any teams that have been eliminated in Champions League being undefeated?
What's the latest round of the competition that such a team has ever reached?
this was their group stage performance.
the above one, their Round of 16 performance. They were out due to away goal.
So they exited Champions League without losing a match that season.
There is one more case of a team eliminated unbeaten in the Champions League. Yet this didn't happen due to the away goal rule in the knock out stage, but after the group stage.
In Season 2002-03 AEK Athens participated in the third qualifying round and proceeded to the group stage with two wins, only to be knocked out after six consecutive draws in their six group matches.
So they were eliminated after a total of 2 wins - 6 draws - 0 defeats.
For questions like this, it might be reasonable to create a CW answer where users of this site might add occurrences they are able to find.
We are looking for teams which did not lose any game neither in group stage(s) nor in knockout phase, but were eliminated after two draws on away goals rule.
